Leonard Cohen, the hugely influential singer and songwriter whose work spanned nearly 50 years, died at the age of 82.

"Unmatched in his creativity, insight and crippling candor, Leonard Cohen was a true visionary whose voice will be sorely missed," his manager Robert Kory wrote in a statement. "I was blessed to call him a friend, and for me to serve that bold artistic spirit firsthand, was a privilege and great gift. He leaves behind a legacy of work that will bring insight, inspiration and healing for generations to come."

Cohen was the dark eminence among a small pantheon of extremely influential singer-songwriters to emerge in the Sixties and early Seventies. Only Bob Dylan exerted a more profound influence upon his generation, and perhaps only Paul Simon and fellow Canadian Joni Mitchell equaled him as a song poet.

Cohen's haunting bass voice, nylon-stringed guitar patterns and Greek-chorus backing vocals shaped evocative songs that dealt with love and hate, sex and spirituality, war and peace, ecstasy and depression. He was also the rare artist of his generation to enjoy artistic success into his Eighties, releasing his final album, You Want It Darker, earlier this year.
